Development of hybrid energy storage solutions: Leading flow battery manufactures are developing hybrid energy storage systems by integrating flow batteries with other storage technologies such as Li-ion batteries and supercapacitors. This is expanding applications of flow batteries in off-grid and behind-the-meter energy storage projects.

Market Opportunities

Rising industrialization in developing regions: Countries in Asia Pacific and Middle East are witnessing rapid industrial growth which is propelling the demand for stable and reliable power supply. This presents significant growth opportunity for flow battery suppliers to establish regional manufacturing bases and supply chain networks.

Increasing smart grid deployments: Smart grid infrastructure development across major economies is a major driver for the deployment of large-scale energy storage systems including flow batteries. This presents lucrative business opportunities for flow battery manufactures worldwide.

Impact of COVID-19 on Flow Battery Market Growth
The flow battery market experienced a decline in 2020 due to the COVID-19 pandemic. Government imposed lockdowns and facility shutdowns disrupted supply chains and lowered demand from various end use industries such as utilities, commercial and telecom towers. Projects were postponed or canceled as customers focused on core operations and delayed CapEx spending. Flow battery manufacturing plants also faced issues due to strict social distancing norms and shortage of labor. This led to reduced production volumes and deliveries in 2020. However, with vaccination drives gaining traction globally, economic activities are restarting in 2021. This is leading to revival in new project awards and announcement of energy storage targets by governments to meet renewable energy integration goals. The market is projected to rebound from 2022 onwards as supply chain disruptions are addressed and customer confidence returns. The long term outlook still remains positive due to favorable policies promoting grid energy storage adoption.

Geographical Concentration in Flow Battery Market

North America accounts for the largest share of the global flow battery market in terms of value. This is attributed to supportive government initiatives for deploying renewable energy coupled with energy storage. Countries like the US and Canada have set ambitious carbon neutral targets that rely on widescale integration of intermittent solar and wind power sources. Flow batteries are emerging as a preferred technology for large scale stationary energy storage and providing ancillary grid services. Europe is another major regional market driven by the EU's Green Deal policy framework. Asia Pacific is expected to be the fastest growing region with China taking aggressive steps to meet its climate change goals through energy transition.

Fastest Growing Region in Flow Battery Market

Asia Pacific region is poised to witness the highest CAGR in the flow battery market during the forecast period. This is due to rising renewable capacity additions in major markets of China, India, Japan and South Korea. China is a global leader in wind and solar power capacity and aims to become carbon neutral by 2060 that will require massive battery based energy storage deployments. India too has set an ambitious renewable capacity target of 450 GW by 2030 driving energy storage demand. Supportive government programs and incentives are attracting investments in storage manufacturing across the region. Falling battery costs along with maturing technology will accelerate commercial and grid scale storage adoption in Asia Pacific.
